Expanded Polystyrene Block-Outs Archway / Arches

<4>How do you create an archway in a concrete wall?

Expanded Polystyrene block-outs, sandwiched between two straight concrete forms, are the easiest, most cost-effective way to create any unique shape in a concrete wall. Six archways, in this Sea Island, Georgia resort, were created using .9 lb. density EPS. Two pieces were used across the bottom and one radiused piece for the top. The wall is 12” thick and the finished arches are 6’ 4” wide and just under 12’ tall. The contractor secured the EPS blocks between straight forms before pumping the concrete. EPS block-outs like these are generally not reusable but many applications are designed so the foam can be reused multiple times.

Universal Foam Products has a patented system for attaching EPS block-outs and form liners to contractor forms, that allows for easy removal after the pour.

“Universal Foam Products was our Geofoam supplier for a stadium seating project in New Orleans. The material was delivered on time and cut to size. We installed the project in less than 3 hours with a 4 man crew without cutting a single piece of foam. We look forward to doing more projects with your company in the future.”
